DETERMINATION PROGRAM DETERMINATION METHOD AND INFORMATION PROCESSING DEVICE
To improve accuracy of abnormality detection using an image.SOLUTION: An information processing device 10 specifies a slope face region 5a occupied by a slope face and a road face region 5b occupied by a road face when a prescribed region is observed from a prescribed position on the basis of measurement data 3a, 3b, ... obtained by measuring the positions of the slope face and road face in the prescribed region. Then, the information processing device 10 detects a partial region in which an object having a possibility of an abnormality is captured on the basis of fixed point observation data 4 including the image obtained by imaging the prescribed region from the prescribed position. The information processing device 10 determines the presence/absence of the occurrence of an abnormality in the prescribed region on the basis of whether the partial region is included in the slope face region 5a or the road face region 5b.SELECTED DRAWING: Figure 1
【課題】画像を用いた異常検知の精度を向上させる。【解決手段】情報処理装置１０は、所定の領域にある法面と路面との位置を計測した計測データ３ａ，３ｂ，・・・に基づいて、所定の位置から所定の領域を観察したときに法面が占める法面領域５ａと路面が占める路面領域５ｂとを特定する。次に情報処理装置１０は、所定の位置から所定の領域を撮影した画像を含む定点観測データ４に基づいて、異常の可能性がある対象物が写っている部分領域を検出する。そして情報処理装置１０は、部分領域が、法面領域５ａに含まれるのか路面領域５ｂに含まれるのかに基づいて、所定の領域における異常の発生の有無を判定する。【選択図】図１
